The Mad Professor pedals are aesthetically luxurious and perform even better then they look. I own “the Little Green Wonder” over-drive and the “Deep Blue” Delay. They both do what they are supposed to do as well as any studio rack device you might want to compare them too. I give them a 10 out of 10!
